Evaluating Laryngopharyngeal Tumor Extension Using Narrow Band Imaging Versus Conventional White Light Imaging

Objective/Hypothesis Comparing detection and extension of malignant tumors by flexible laryngoscopy in the outpatient setting with under general anesthesia using both White Light Imaging (WLI) Narrow Band (NBI). Study Design Prospective study. Methods Two hundred thirty-three patients laryngeal pharyngeal lesions underwent rigid laryngoscopy, WLI NBI. Extension (n = 132) was compared between techniques detail. Results Sensitivity NBI during endoscopy (92%), comparable that (91%). The correlation tumor high (rs 0.852–0.893). observed significantly larger when settings. use leads to upstaging (12%) downstaging (2%) T classification. Conclusions could be an alternative endoscopy. improves visualization accuracy staging. Level Evidence 3 Laryngoscope, 131:E2222–E2231, 2021
